Need Windows source code or possibly DLL for WordWeb (see [url removed, login to view]) to get the word under the cursor when the user presses a hotkey. Babylon does this rather well, mostly using OCR - something similar and equally reliable is required for WordWeb. The code must be very reliable and robust (product is installed around 100,000 times a month) and light on system resources.
Minimum list of applications feature must work with: Word, IE, Firefox, Acroread, Notepad, etc, but the function should be general. Not urgent.
